which the following is a specification;

My invention relates to the improvement of rubber heels of that class which are adapted to be connected with a leather. shoe and has partiofularrelation to the improvement of the construction set forth in my former Letters Patent-No. 850,156 issued under date of April 16, 1907 The objects of my present invention are to provide improved means for detachably connecting a rubber heel with a shoe; to so construct and arrange the. attaching means and rubber heel as to admit of the heel body being readily engaged with or disengaged from the attaching deviceland to .so construct my improved attaching'device as to obviate the necessity of employing a spring plate or other spring member in connection therewith and at the'same time reserve the resilience or yielding action of t e heel.

A further object consists in so constructing and connecting the attaching device with the heel as'not to lmpalr the wearing quality or resilience of the rear portion of;

the heel, which is ordinarily subjected to the greatest pressure.

5 These objects I accomplish in the manner illustrated in the accompanying drawing, in which I Figurel is a central lon 'tudinal section of myimproved heel-showing the same attached to a shoe. Fig. 2 is a plan view of the attaching plate or frame,and,. Fig. 3 lis t e attaching plate connected therewith an disconnected from the shoes Similar numerals refer to similar parts throughouttheseveral-views.

1 represents a rubber heel body of suitable size and contour, the upper side of said heel body having formed therein a socket 2 which with the exception of having its rear end slightly curved, is substantlallyl As indicated at -3, the.

square' in outline. heel body is formedat the base of the forward portion of the socket 2 with a forwardly extending horizontal recess 3 and at the base of the rear portion of the socket thickness of solid rubber.

with a rearwardlyextending horizontal recess 4 of less-length than the recess 3.

5 represents the attachi member whichis in the nature of a metal ame preferably aluminum, whichfru-nie has projecting rear wardly from its base a' curved lip 6 and from the base of its forwardportion a somewhat longer lip 7. i The body ,of the frame plate 5 is ofsuch size as to fit snugly within the socket2 of the heel bodyv 1 and is formed a at its corners and at the center of the length of the front bar of the frame with enlargements '5 through which enlargements'are formed nail holes 8.

The metallic frame plate'formed as described, is as indicated more clearly in Fi 1 of the drawing, to be rigidly connected with the heel carrying base 9 of the shoe or with the first leather heel lift 10 ofthe shoe, by

,forcing nails 11 upward through the holes 8 of the frame plate, thence into the heel carrying base" of the shoe through the lift 10. It isobvious, however, that the lift 10 may be omitted and the heel attached directly to the shoe base or rear'portion of the sole.

When the frame plate is thus-connected I with the shoe body, it will beunderstood that a rubber heel constructed as herein described, may be readily connected with said frame plate by so bending and manipulatmg the heel as to cause'the lip 7 to enter and fill the heel recess 3 and the lip 6 to enter and fi-ll in a like manner the recess 4. When the rubber heel is thus engaged with the attachin device, itwill be'understood that the natura tendency of the heel body to lie in the proper horizontal position, w1ll serve to retam it in' connection with thefframe plate.

Owing to the fact that the body of the attaching device is in the nature of an open frame, it is obvious that the yielding action of the rubber at-the central'p'ortion of the heel, will 'not be retarded or the resiliency of' the heel aifected. It will also. be noted that the attaching lips 6 and 7 are compara.-,

and in. front'of the 11p 7, a ,considera le It will also be observed that I have formed the rear 1i i 6 of length than the forward lip 7, t us insuring a greater thickness of solid rubber at the rear portion of the heel which is ordinarilysubjected to the greatest wear and pressure. It will thus be seen that my improved attaching device, is' so formed and connected with the heel as to present the least opposition to the resiliency or yielding action of the rubber.

It is obvious that by the construction here- 'in described, a worn rubber heel may be readily detached from a shoe and a new heel attached in place thereof;

From the foregoing description, it will be seen that simple and efficient means are herein provided for accomplishing the objects of the invention, but While the elements shown and described are well adapted to serve the purposes for which they are intended, it is to be understood that the invention is not limited to the recise construction set forth, but includes within its purview such changes as may be made Within 'the scope of the appended claim.

What I claim, is

In a rubber heel, the combination with a shoe and a horizontally disposed plate having a body in the nature of an open frame attached to said shoe, said frame plate having forwardly and rearwardly extending base lips, of a rubber heel body having an upper side socke't adapted to receive the frame plate and having lateral recesses at the base of said socket.

In testimony whereof I aflix my signature in presence of two witnesses.
